Canada and the US miss Wednesday's deadline and at least partial 50-percent tariffs on Canadian goods take effect on schedule August 19, 2026.
The wording, the opening probability, and the counter-signal below were fixed when this call was published. Updates revise the reading — never the record: the verdict is graded against the opening call.
The trajectory
The record since
- 19 Aug 26 Trump paused the scheduled 50-percent tariffs three days before the Aug. 19 deadline rather than letting them take effect on schedule, squarely against this call.
What would overturn it
A last-minute Greer-LeBlanc breakthrough announced before August 19 would overturn this; talks were described as constructive but negotiators still far apart as of Monday night.
The verdict
Miss Resolved 24 Aug 26.
Trump paused implementation on Aug 18 citing a tentative deal; tariffs did not take effect at 12:01am Aug 19 as the claim required (they took effect Aug 22 after talks later collapsed).
The 'deadline miss + tariffs land on schedule' framing didn't account for a last-minute pause-pending-paperwork outcome.
As logged at issue
Roughly even odds Canada and the US miss Wednesday's deadline and at least partial 50-percent tariffs take effect on schedule — talks remain "constructive" but negotiators were still described as far apart on autos and dairy as of Monday night; a last-minute Greer-LeBlanc breakthrough is the signal that would overturn this.
